摘要
铝合金试样经处理后,在适当的酸度下用碳酸钙沉淀分离铝,所分离的滤液调整到合适酸度,加入甘露醇,用氢氧化钠标准溶液滴定至红色。加标回收率在97.60%-102.67%。
After dealing with aluminum alloy sample ,Calcium carbonate deposit aluminium at proper acidity, filter liquor is adjusted to proper acidity,adding manna sugar ,Sodium hydroxide standard solution titrate to red.results of recovery tests found were in the range of 97.60%-102.67%.
